Course content

The subject covers the issues of gas turbine engines (GTE) and encompasses key areas, such as fundamental flow theory in turbomachinery, thermodynamics of GTE cycles, description of design solutions for axial and radial compressors, gas turbines, and combustion chambers. Within the exercises, practical examples are addressed, including the analysis of the thermodynamic GTE cycle, calculation of fundamental parameters of radial or axial compressors, and simplified design of a single-stage gas turbine. The exercises are complemented by laboratory tasks carried out using the educational model of the gas turbine ET-792 and the air turbine VT-400. Contents of the lectures: 1. Basic equations. 2. Introduction to gas turbine engines theory (GTE). 3. Thermodynamics of basic GTE cycles. 4. Radial compressors. 5. Axial compressors. 6. 2D flow in axial compressor blade cascade. 7. Methodology of axial compressor stage preliminary design. 8. Combustion chambers, combustion process, ecological consequences of combustion. 9. Axial gas turbines. 10. 2D flow in axial gas turbine blade cascade. 11. Methodology of axial gas turbine stage preliminary design. 12. Axial gas turbine blade cascades loss models. 13. Axial gas turbine cooling. 14. Introduction of ET-792 gas turbine educational model. Contents of the exercises: 1. Optimal compression ratio of GTE compressor. 2. Heat savings calculation using GTE cycle with regeneration. 3. Example of radial compressor parameters calculation. 4. Example of single-stage axial transonic compressor parameters calculation. 5. Simplified design of single-stage axial gas turbine. 6. Laboratory exercises (educational model of gas turbine ET-792, experimental air turbine VT-400).
